Abstract

The invention discloses a nanomaterial formula for use in stainless steel precision polishing and a preparation process thereof, and belongs to the technical field of high-molecular materials. The nanomaterial formula is prepared from the following components in parts by mass: 50 to 90 parts of nanometer flaky alumina polishing powder, 50 to 90 parts of cerium oxide-silicon oxide compound polishing powder, 0.05 to 2 parts of polishing accelerant, 0.05 to 3 parts of polishing agent, 0.05 to 2 parts of PH regulator, 0.05 to 1 part of corrosion inhibitor, 0.01 to 0.1 part of stabilizer, 0.05 to 0.5 part of chelating agent, and the balance of deionized water. According to a stainless steel precision polishing nanomaterial and a preparation method thereof, the advantages of the nano-flaky alumina, spherical cerium oxide and nano-silicone oxide are combined in the nanomaterial; a flaky material and a spherical material are combined scientifically in a scientific and reasonable mixture ratio, so that the removing rate of the nanomaterial specific to stainless steel in a stainless steel polishing process is increased, and meanwhile a steel material can have a mirror surface. Moreover, the polishing powder used in the preparation process is easy in preparation method, has high stability, is relatively low in cost, and does not cause environmental pollution or equipment corrosion.

Description

technical field [0001] The invention discloses a nano material formula for material polishing and a preparation process thereof, in particular to a nano material formula for stainless steel precision polishing and a preparation process thereof. Background technique [0002] Polishing powder is widely used in the industrial field. According to different purposes, there are many types of polishing powders such as industrial diamond, aluminum oxide, iron oxide, etc. Among them, iron oxide has been used for grinding flat glass for about 40 years since the end of the nineteenth century. Polishing material for optical glass etc. The history of the development of rare earth polishing powder can be traced back to the First World War. The United States and Canada took the lead in using rare earth polishing powder mainly composed of oxide decoration for the grinding of precision military machines such as anti-aircraft gun sights, replacing iron oxide polishing powder Compared with ir...
